My invention relatesto cotton gins, and

more particularly to the I picker roll, which agitates the cotton so asto-feed it to'the gin saws in shape so that the said saws engage the lint'of thecotton. V a U a My invention is applicable to any ordi nary type ofcotton gin, and has for its purpose to provide an agitator roll adjacent the forward side ofthe gin saw cylinder which will agitate the cotton and also, prevent the passage of the bolls of cotton downwardly past said agitator roll andawayfrom the saws.

Idesire'to provide an agitator roll, which will be adjustable to and from the saw'cylin-.

derfso as to accommodate different sizes and grades of cottonwhich are fed into the gin,

relative to the gin saws and at both ends of the shaft at once without difliculty.

In the drawing herewith, Figure 1 is a broken detail partly in section throughthe forward side of a cotton gin, and illustrating the manner in which the adjustment of the picked roll is obtained.

Figure 2 is a broken plan view partly in section through the gin housing and showing an arrangement whereby the roll isadjustable at both ends simultaneously.

In the drawing the housing 1 of the gin is shown only in a fragmentary way. The gin saws 2 are mounted upon a shaft 3 rotatable in a counter-clockwise dlrectlon as seen in Figure 1. The cotton fed downwardly through the passage 4 to the rear of the gin breast 5 is discharged against the picker roll 6. i

The gin breast 5 is formed upon a frame, the upper end of which is extended'slightly to the rear at 6 and pivoted in the frame at the gin breast.

It is, therefore, adapted to swing between the of the gin housing toward and away from the saw cylinder, toward the lower side 7 of the gin breast is a deflecting board 8, which is curved inwardly to a point closely adjacent the picker roll 6, and is provided with prongs ,9, which are adapted to interfit with the inclined spikes 10 projecting from the picker T011. 1 Y 7 The spikes 10 upon the picker rollare adapted to interfit between the saws 2 of the saw cylinder and also between the prongs 9 at the lower end of the deflecting board 8,

. and thus assures that no cotton be allowed to pass the agitator roll in, the feeding of the cottonto the saws. c r e The picker roll 6is mounted upon a shaft 11 which is supportedat its ends in bearings12, secured at one'end of a plate 13;

Said plate 13 is extended toward the for-' ward side of the gin, and its outer'end'is isformedinthe plate. On thenpperside ofsaid opening are a plurality of rack teeth .16, whichare adapted to be engaged by a pinion17. There are two pinions 17 engageable withflthe two racks 16 at each side of thegin to support the two ends of a shaft 11'. These pinions are fixedupon ashaft 18 and are ro-' tatable therewith. Said shaft 1 is rotated through a lever arm 19 fixed to the shaft'a nd proj ecting upwardly along the side of, t-he ginhousing; It has a latch member 20;thereonywliiclimay engage with a. sector'shaped rack 21 on the side of the housing. Thislatch I 0 formed with a rounded bumper. 14,,which' bears against the swinging end portion i 5 of Between the endsiof the plate an elongated oval shaped opening may be manipulated at the handle by' means of a projecting'a'rm 21 on said latch.

.The plates 13,:which support the ends of the picker'rolhare slidable within a slideway formed between two opposite plates 22. Said plates have an overhanging flange thereon behind whichthe plates 13 are engaged and allowed to slide. It will, therefore, beseen that the plates at both ends may slide simultaneously through the rotation of the pinions 17, rotatable through the handle 19' I fixed thereto. .It will also be noted that this adjustment maybe made to very slight degrees gin breast will, of course, carry the prongs 9 on the deflector boa-rd 8 along with the same and thus allow the interfitting of the teeth 10 011 the picker roll with said prongs inthe same adjustment at all times. hen [the shaft is moved inwardly carrying the picker roll closer to the gin saws, the gin breast 5 will follow along with the plate 13 by gravity due to the pivoting of said gin breast at the point 7 as previously noted. v

The advantage of this structure lies in the convenient manner in which the adjustment may be accomplished without the aste of any material amount of time; The picker roll can be moved without loosening any nuts or making adjustments at the ends thereof, but all that is necessary is asimple swinging [of the lever arm 19 to obtain the adjustment desired, and this arm may be secured in adjusted position by means of the latch in the manner described; i WhatIclaim asnew is: i v Y 1.. In a cotton gin including a saw cylinder, a rotating toothed roll positioned in front of said journals,

I platessupporting said journals, slideways for said plates, said plates having elongated openings therein, racks in said openmgs, pinions in said openings engaging said racks and means to simultaneously rotate said pinions-to move said plates and slide said roller to or from said cylinder.

' V 5. In a cotton gin including a saw cylinder 'a rotating toothed roll positioned in front 0 said saw cylinder, a shaft for Sharon, 5!. longitudinal -slidable plate supporting each of the endsof said shaft, upper and lower slide- "ways 'for said plates allowing a. free length wise sliding movement of said plates therein, and means engaging said plates to slide said plates and said shaft in a direct line toward and from said cylinder. r

. 6. Ina cotton gm a saw cylinder, a shaft parallel thereto, a spiked roller'mounted on saidishaft, journals at the ends of said shaft, longitudinally 'slidable' plates supporting horizontal -slideways for said plates, a deflector board adjacent said roller and means to slide said plates there:- in to adjust the position of said rollerand simultaneously adjust said deflector board relative to said cylinder.
